Vista. Am now on a Windows 7 64K machine and problem persists. Frequently when I come back from Hibernate mode Firefox says it is offline, won't go back to online. Close the browser. Then reload w/ icon, says firefox is already running, have to use task manager to close the process in order to use it again. Used firefox for years w/out this problem. As it is happening on 2 different machines and operating systems, I have to think it was introduced sometime in the last 6 months. Reproducible: Sometimes Steps to Reproduce: 1.Use firefox 2.Hibernate or sleep machine 3.Use machine again - if firefox tabs say loading and stay that way AND/OR says working offline, close window, restart firefox error says already running, must use task manager to close in order to open a new session. Actual Results: as above. Expected Results: should have closed firefox.exe w/out having to use task manager. None
This usually is caused by an extension. Please try running in Firefox safe mode.
Considering that the above comment was a solution to the problem (since the reporter hasn't responded in over a year), I'm going to mark this bug as Invalid. Reporter, if you can still reproduce this bug in the latest version of Firefox, please reopen this bug.
